' Beit known that I, Aooos'r J. Rees/roan,

a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Conveyers, of which r the following is a specification.

This invention relates principally to endless power conveyers of thetype commonly referred to as"-carryalls or carrousels for conveying heavy or bulky articles, such as cans containing milk or' ice cream and trays containing bottles and has for its principal objects to reduce the friction between the article"supporting elements and the parts over which said elements travel, to

.obtain an even continuous motion of the 1 "article supporting elements, to eliminate the use ofcastors for supporting said elements,

to increase the number ofsup'ports for said ,elein'ents and to simplify the construction and to reduce the cost of manufacture. The inventionconsists principally in the improved manner of supporting the article supporting elements; and it also consists in the combinations and arrangements of parts hereina er described and claimed.

In" the 'accompanyin drawing, which forms part of-this 'speci cation, and wherein like reference numerals refer to like parts whereverthey occur,

,- Fig. lfis a plan viewof a portion of an endless power conveyer embodyingmy in-' ventlon, parts being, broken away to more clearly illustrate the invention;

Fig-.- 2 is a vertical longitudinalsectionon the line 2-2 in Fig. 1; and v Fig. -3 is a vertical cross-section onthe line 3-3 in Fig. 2. i

The accompanying drawing illustrates a portion of one side of an endless conveyer, the .ends and the opposite side of the conveyer being omitted. The frameof the con- -veyer is preferably constructed of angle irons and comp-rises a pair of horizontally extending spaced parallel angle iron side rails 4. The side rails 24 of the conveyer frame are disposed with their vertical flanges up and with their horizontal flanges down and facing outwardly. The side rails are supported at intervals throughout their length by pairs of oppositely disposed vertical members 5. The upper ends'of the members 5 are secured to the bottom flanges of the side rails 4: by angle brackets 6 and 1921. Serial no. 483,751.

are connected at'their lower ends by a bottom cross-memberi Projecting upwardly ate cross-zne1nber 8, which is secured to the pair of vertical members'5, is apair of vertical memberst). .Secured to the opposing faces of the members 9 is a painof spaced plates 10, whichconstitute guides for one stretch of'an endless link chain 11, which passes around sprocket wheels (not shown) at the ends of the conveyer. The

guide plates lOare supported at intervals along their length by means of angle strips 12', which ,jhave one flange secured-to the Y outer face'of a guide plate and the other flange secured to the under side ofthe bot-v and are held on the studs by nuts 17. The studsare disposed in horizontal alinementat a height that will bring the upper surfaces of the rollers thereon above the tops of the side rails 4.

Supported on the. rollers 14 are article supporting-devices comprising blocks 18 of wood or other fibrous substance. Thin mefrom an intermedi-F cated along the inner faces of the side rails 1 tallic Wear plates 19 are secured to the under sides of'the blocks 18,- said plates being f azsize andshape corresponding to the size and shape f said blocks. The blocks 18 are connected to the chain 11 b means of U-shaped brackets 20, where y said blocks are adapted to be propelled by the chain over the bedof supporting rollers 14 and serve as a means forsupporting said chain. The webs of the brackets 20 are riveted or otherwise rigidly secured to the uppermost links of the chain I1; and the spaced vertical branches of said brackets are provided at their upper ends with ORV wardl'y projecting horizontal. portions which are rigidly-secured 'tothe' middle portion of the blocks 18 by bolts 21.

Guard rails 22 extend longitudinally of theconveyer above the side railse thereof and are supported from said side rails by' vertical straps 23. The rollers. on one side rail are disposed oppositeto the spaces between the rollers on the other'side rail. v This staggering of the supporting rollers results in a more equal distribution ofthe supporting points and eliminates the tendency of the blocks 1 to tilt during the passing of the end por-' tions thereof." over the spaces between the rollers.

#nm use of the roller supports eliminates :to 'provide' clearance between the inner cor- 'thenec'essity for supporting theblocks on tracks '10 means ofxcastors, which bind and .drag w en traveling around the curved portion of the conveyer, and. also-enables the number of supporting points-to be increased, whereb a smoot and even movement of said books ovensaid su porting rollers is obtained. As shown in t e drawing, the inner corners of the-blocks l8 and the wear plates 19 are beveled or copedoif ners of adjacent article supporting devices during their travelaround the curved portions of-theconveyer.

4 It is evident thatl modifications in the formsof the parts may be made and that M le,

the inveniton' is not restricted to the precise forms shown in'the drawing,

Whatlelaimis: I 1. A conveyer comprising spaced side rails and spaced guide members located therebelow, a chain running between said guide members, rollers journaled on said side rails, article supporting devices movable thereover, and means for connecting said article supporting devices with said chain, said nieans comprising U-shaped straps having their web portions secured to 40 'said chain and having their branches secured to the under sides of said article supporting devices.

2. A conveyor comprising, spaced side rails and spaced guide members located 4 .therebelow, a chain running between said" guide members, rollers journaled on said rails between the opposing faces thereof,
